Embodiment Construction

[0020] Such as Figure 2A As shown in , one embodiment of the present invention includes an adsorber 200 that incorporates vertical baffles 208 in the adsorption vessel 200 to increase the raw gas flow rate through the vessel without causing fluidization. The vertical baffle 208 incorporated in the adsorption vessel 200 includes a vertical portion or plate 212 secured to a horizontal or semi-inclined horizontal portion or plate 210 . For example, the vertical portion or plate 212 may be welded or secured to the horizontal or semi-inclined horizontal portion or plate 210 using any other means suitable for securing similar materials together. For the sake of brevity, reference is made hereinafter to conventional welding means, however, in no way restricting the present disclosure to welding only. Vertical baffle 208 may also be a single plate 211 that has been bent or otherwise molded into a curved shape, such as, for example, Figure 2B as shown in. refer to Figure 2A, the...

Abstract

An adsorber vessel for the adsorption of gas contaminants from a gaseous stream comprising a vertical wall baffle positioned on an inner surface of an absorber vessel wall, and a bed support positioned below the vertical wall baffle and affixed to the inner surface of the adsorber vessel wall to support an adsorbent material, where the adsorbent material is interned by the bed support, the adsorber vessel wall, and the vertical wall baffle such that at least 90% of the volume created between the vertical wall baffle and the inner surface of the adsorber vessel is free of the adsorbent material.

Description

technical field [0001] Air separation plants generally include adsorbers or adsorption vessels to remove contaminants, such as carbon dioxide, water, hydrocarbons, etc., from the air before it enters the air distillation plant. Classical adsorber designs use cylindrical vessels, where the minimum cross-section of the cylindrical adsorption vessel is determined by the maximum allowable flow rate of the ascending gas stream (eg air). Cylindrical adsorption vessels can be positioned vertically or horizontally based on the requirements of the vessel. For both vertical and horizontal adsorber configurations, the maximum allowable flow rate of the ascending gas flow is set by fluidization (ie, the velocity at which the feed gas can raise the adsorbent). This is especially true at the bed surface, and in the case of a horizontal vessel configuration, near the bed surface near the inner vessel wall. Background technique [0002] Such as Figure 1A As shown in , a conventional hori...
